As Democratic Senators Barack Obama of Illinois and Hillary Clinton of New York slug it out for the nomination, many of their supporters -- at least in Pennsylvania, site of the next major primary -- aren't committed to the party's ticket in November, according to a Franklin & Marshall College Poll.

Among Obama supporters, 20 percent said they would vote for Sen. John McCain of Arizona, the Republican nominee, if Clinton beats their candidate for the nomination. Among Clinton supporters, 19 percent said they would support McCain in November if Obama is the Democratic nominee.</div></div>
